Tokina AT-X 16-28mm F2.8 PRO FX (Full Frame)
Lens For Canon: This new Tokina lens is the first in a new generation of full
frame (FX) lenses designed for professional digital SLR cameras like the Canon
EOS 5D Mark II. The 16-28mm zoom range gives the professional photographer a
super-wide angle of view to get close to subject for remarkable effect or to
take in entire scenes.

The AT-X 16-28 f/2.8 uses a newly developed silent DC motor that allows the lens
to focus faster and more quietly then previous generations. The DC motor coupled
with a new GMR magnetic AF sensor work together to increase AF Speed. Tokina’s
special One-touch Focus Clutch Mechanism allows the photographer to switch
between AF and MF simply by snapping the focus ring forward for AF and back
toward the camera to focus manually.

The Tokina AT-X 16-28mm f/2.8 Pro FX features 16-28mm at focal length with
maximum aperture of f/2.8. The lens construction has 15 elements in 13 groups
and has diagonal angle of view at 107 degrees with filter size of 1:5.26. The
Tokina AT-X 16-28mm f/2.8 Pro FX lens weighs 33.51 oz. (950g) and it measures
3.54″ (90mm) in diameter and 5.25″ (133.3mm) long.
